Well process accounting directly tracks user processes. The kernel's pacct
file will contain the actual CPU time and memory usage of all applications
started by users. In doesn't know about what the processes are
specifically doing, just how hard they worked. You might choose to augment
or vet the data collected by arbtt with this kernel data.
